Description
Technical Field
The invention relates to the field of emission control of fine particulate matters in fossil fuel combustion flue gas, in particular to a device and a method for absorbing and filtering PM2.5 by coupling Taylor vortex and chemical agglomeration.
Background
The air pollution in China is changed from the traditional bituminous coal type pollution into the cross-regional and compound pollution mainly comprising PM2.5 and the like. Fine particles (PM 2.5) refer to solid particles or liquid droplets with an aerodynamic diameter of less than or equal to 2.5 μm, also known as lung particles. The size of the particles produced in industrial production can range from sub-micron molecules to millimeter coarse particles, wherein the mass fraction of PM2.5 is not large, but the quantity proportion can be more than 90% of the total number of particles. Because the particle size of fine particles is very small, the traditional conventional dust removal equipment is difficult to effectively remove, therefore, a pretreatment device is additionally arranged in front of the dust removal equipment, and the fine particles are agglomerated by a physical or chemical method, so that a method for removing the formed larger particles is the development trend of the current dust removal technology.
The adsorption filtration is the most widely used method in the gaseous pollutant treatment technology, the coarse filtration cotton is economical and applicable, safe and environment-friendly, and convenient to use, can be cut out automatically according to the size of the air outlet, can be directly installed, can also be made into a plate type, folding type or bag type filter for use, is the most common filtration material used in industrial waste gas treatment and purification filtration, and is the most common filtration material used. However, the coarse filter cotton can only filter particles larger than 5 μm, has no filtering effect on fine particulate matters, and still faces the technical problem that PM2.5 in industrial flue gas cannot be removed. The larger the particle size, the better the filtering interception has the effect of removing the particles, and the PM2.5 can be removed after growing into larger particles through physical or chemical action. Commonly used methods for PM2.5 particle growth include acoustic agglomeration, magnetic agglomeration, chemical agglomeration, electrocoagulation, and the like; among these measures, acoustic wave agglomeration and magnetic agglomeration have not been applied in the industrial field, and electrocoagulation has primarily met the conditions for industrial application, but the cost of construction and operation is too high. The chemical agglomeration technology can increase the particle size of PM2.5 particles under the condition of not changing normal production conditions and existing dust removal equipment and operation parameters, so that fine particles can be effectively intercepted by the filter cotton, and the amount of PM2.5 discharged into the atmosphere is reduced. But the single chemical agglomeration technology has poor agglomeration effect on PM2.5, and is difficult to fully agglomerate fine particles to enable the diameters of the fine particles to reach 5 mu m and be intercepted by filter cotton, so a device and a method for filtering PM2.5 by coupling Taylor vortex and chemical agglomeration absorption are provided.
